The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will automati-
cally begin to flash.
The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY/
TIMER lamp flash indicators is listed in the instruction manual for the user's knowledge and reference. If an error
symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in
memory to reveal past problems and how often these problems occur.
1. DIAGNOSTIC TEST INDICATORS
When an errors occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the
problem. If there is more than one error, the lamp will identify the first of the problem areas.
Result for all of the following diagnostic items are displayed on screen. No error has occured if the screen displays a "0".

Symptoms
· Power does not come on.
· No power is supplied to
the TV.
· AC power supply is faulty.
· Power does not come on.
· Load on power line is
shorted.
· Has entered standby state
after horizontal raster.
· Vertical deflection pulse is
stopped.
· Power line is shorted or
power supply is stopped.
· No raster is generated.
· CRT cathode current
detection reference pulse
output is small.
· Power is shut down
shortly, after this return
back to normal.
· Detect Micro latch up.
Note 1: If a + B overcurrent is detected, stoppage of the vertical deflection is detected simultaneously.
The symptom that is diagnosed first by the microcontroller is displayed on the screen.
Note 2: Refer to screen (G2) Adjustment in section 3-4 of this manual.
*R(Q703), G(Q702) or B(Q701) out is faulty (C6 board).
